Clear answer

Clear answer, explained.

It identifies inefficiencies, over- or under-lighting, and opportunities to improve performance with LED upgrades and controls. The audit provides the data needed to design an effective lighting solution, estimate energy savings, calculate ROI, and ensure compliance with lighting standards. While small projects may proceed without a full audit, most commercial upgrades benefit from this step to avoid poor design or missed savings opportunities.
